I been researching whether or not AAP 2.5 will run on a Single Node Server and have read conflicting reports…I am hoping someone has been able to get AAP 2.5 running on a Single Server System.  
The name of my Server is “[f-ansible1.mydomain.com](http://f-ansible1.mydomain.com)” and I am trying to make it the AutomationController, AutomationGateway, Automationhub, and Automationedacontroller. Will this work?

As far as I know, 2.5 requires at least 2 nodes, as some functionality cannot be on the same host.

I tried it with this inventory, which works.

```auto
[automationgateway]
gw01
[automationcontroller]
cn01
[automationhub]
ah01

```

The “correct” single-node approach going forward is to switch to the containerized deployment method.

There’s checks within the RPM installer that prevent you from co-locating the automation gateway and controller on a single machine, so unfortunately to use the RPM-based installer, you’ll need minimum of two machines.
